Let's get you to where you want to be!

3 + 5 = 8 shows that 3 hot dogs are sold for every total 8 hot dogs + hamburgers. With a total of 80 hot dogs + hamburgers, we can write our proportion equation as:

3 / 8 = x / 80

or

__3__ = __x__

8 80

Since the ratio must remain the same, and you multiply 8 by 10 to get the total 80, we can also multiply 3 by 10 to get the correct number of hot dogs, 30.

x = (3 / 8) x 80 = 30 hot dogs
